Although pre-orders aren't available locally, the new Valve Index is the company's first-party SteamVR hardware offering that bundles a headset, controllers, and base stations for $999 USD. Or $499 for just the headset. With the new headset offering 1440x1600 resolution per eye (same as the
HTC Vive Pro) in addition to a wider FOV and fill-rate to minimise the "screen door" effect.
This is very much a premium VR solution from Valve - with the headset even supporting a VR-first 144Hz refresh rate. The headset includes over ear speakers that do not touch your ears too, in addition to stereo cameras on the front. Full specs for the headset as follows:

Where it gets interesting though is with the new controllers designed by Valve which allows for full open hand interaction in addition to being able to accurately measure 'squeeze'. "Each controller uses 87 sensors to track hand position, finger position, motion, and pressure to determine user intent," states the official description. "All of these signals, combined with fine-tuned software and algorithms, give us a better understanding of how a player is holding and using the controllers." Combined with the base stations they present the most immersive room-scale VR to date allowing users to naturally pick up objects, throw them, and even use individual fingers to interact with stuff in a virtual space.
Traditional buttons are also included and as a device from Valve the Index is fully compatible with all existing SteamVR software - and future stuff too. Like the upcoming VR update coming to No Man's Sky. As per the previous Steam store page leak the minimum specs are:
SYSTEM REQUIREMENTS
OS Windows 10, SteamOS, Linux
RAM 8 GB+
GPU NVIDIA GeForce GTX 970+ or AMD RX480+ (Available DisplayPort required, HDMI not supported)
